Course Description

This unit of competency sets out the knowledge and skills required to apply fluid mechanic principles in mechanical engineering. This includes the principles and applications of fluids, fluid components, fluid status, fluid flow, fluid power, and forces developed by flow in fluids. To perform calculations to determine changes, forces etc, fluid flow, head loss in pipes and through open channels, to determine operational aspects of a pump in a system and to describe the basic types of fluid machinery.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. However, practice in this unit is subject to regulations directly related to occupational health and safety and where applicable contracts of training such as apprenticeships and traineeships.

Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor.

Feeback will be provided throughout the course

Evidence can be gathered through a variety of ways including: observation of processes and procedures; oral and/or written questioning on required knowledge and skills; testimony from supervisors, colleagues, clients and/or other appropriate persons; inspection of the final product or outcome; a portfolio of documentary evidence.

Graded Assessment out of 100 Marks will be based on the results obtained for Assignments/Practical reports/Unit tests/Exams.

Students must gain pass in all forms of assessment in order to pass the competency.
